I am here again with another DIY which I am about to perform and need your guidance. I have a Cultus stock cassette player and want to add the mp3/bluetooth module connections in it. I have opened it up and found the L/CH and R/CH at the tuner section which then go to Audio IC PT2313L and then go to speakers from there.
I want to ask can I solder my AUX Right and Left channel input to those R/CH and L/CH pins and it would work? or do I need to do some other mod as heard somewhere that we need to disconnect radio AM connection for it to work. I am attaching the images so you gurus can better understand.
On left side you can see pins with labels (on opposite side is the tuner) -> http://tinypic.com/r/ztdxrd/9
